To all whom it may concern:

' Be it known that l, BERNARD ivinrrmnos, a citizen of the United States, residing at Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Pu np Attachments for Automobiles, &c.; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the ant to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part oithis specification.

This-invention relates to new and usefulimprovements 1n pump attachments for automobiles oi various kinds and the ob ject in view is to produce a simple and etficient device of this nature so arranged. that the pump may be attached to the frame of the vehicle and the piston to the rear driving wheel, the power vwheel being jacked up so that, when the wheelie rotated, the pump may be operated.

The invent on comprises a simple and si ficient clev c of this nature having various details of construction and combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claim.

1- illustrate my invention in the accompanying drawings, in which 'de elevation showing; the

clamp which holds the pump to the run-- ning; board in order that the swamp niay oscillate as the wheel rotates. A collar, designated by letter F, is clamped about the circumference of the hub and has an arm projecting therefrom, grooved at its end asat H to receive a bar 0, having a clamping member Q at one end for engagement with it spoke S of clear wheel, and to'said bar is fastened the threaded end of the piston at T, there being a suitable hinged joint l provided in order to allow the piston to recipro cate as the wheel rotates. Bythe' provision of a device embodying the features of my invention, it will he?- noted that means is afforded whereby anordinary air pump may be "attached to the running board of automobiles of-vario'us ll1ZkGS,Wl1ii$ the power for operating the pump is derived from an attachment to the hub and spoke oil-a wheel, makingtlle device. applicable to any type of vehicle? In operation, the wheel which operates the pump is jacked up' in order that it may be out of contact from the ground and made to rotate by the operation of the engine, while the pipe W may be attached to'any so one of the tires for inflating the some. When thedevice is not in use, it may be readily detached from the vehicle,'as will be readily understood.

What I 'claiintohe new is:-

In combination with a spoke wheel, has having a "forked end provided with eon-'- caved resilient arms adapted to engage a spoke of said wheel, the ends of the airl ne projecting beyond the latter and parallel 9G with eac other, a thumb screw passing through registering apertures in said petal lel ends, second bar adapted to he ifasv toned at one end to the hub of the wheel, its other end forked and provided with holy; caved resilient for engagement wit said spoke engaging bar, and means he clamping the bars together, the end of the spoke engaging bar designed forattacli ment'to a reciprocating rod.
